    Some of the better amps have protection against that, but some of the lesser ones don't. You're going to want to open that up and look for any burn marks or something that looks awry. You're sure nothing else is wired wrong?

    Disconnect fuse and retry. I did this one time by mistake. Luckily nothing happened to my amp.

    You might have let the magic smoke out. Check fuses. If that doesn't fix it open it up and see if anything is burnt.

    Oh, those small fuses definitely should have blown first. What size wire?

    they may have been under stress when you wired them wrong and when powered back up just blew

    You're going to want the same size power and ground wires.

    ^^^This. Go back and re-check everything. If you find no fuses blown, and you're sure the wiring is done right, open that amp up.
